r249685, r249686: r249668: Use procstat_getprocs(3) for retrieving thread information instead of direct sysctl calls. r249669: Use more generic procstat_getvmmap(3) for retrieving VM layout of a process. r249671: Use procstat_getgroups(3) for retrieving groups information instead of direct sysctl. r249673: Use procstat_getumask(3) for retrieving umaks information instead of direct sysctl. r249675: Use procstat_getrlimit(3) for retrieving rlimit information instead of direct sysctl calls. r249678: Use libprocstat(3) when retrieving binary information for a process. r249680: Use libprocstat(3) to retrieve process command line arguments and environment variables. r249683: Use libprocstat(3) to retrieve ELF auxiliary vector. r249685: Use procstat_getkstack(3) for retrieving process kernel stacks instead of direct sysctl calls. r249686: Make use of newly added libprocstat(3) ability to extract procstat info from a process core file. So now one can run procstat(1) on a process core e.g. to get a list of files opened by a process when it crashed: root@lisa:/ # procstat -f /root/vi.core PID COMM FD T V FLAGS REF OFFSET PRO NAME 658 vi text v r r-------- - - - /usr/bin/vi 658 vi ctty v c rw------- - - - /dev/pts/0 658 vi cwd v d r-------- - - - /root 658 vi root v d r-------- - - - / 658 vi 0 v c rw------- 11 3208 - /dev/pts/0 658 vi 1 v c rw------- 11 3208 - /dev/pts/0 658 vi 2 v c rw------- 11 3208 - /dev/pts/0 658 vi 3 v r r----n-l- 1 0 - /tmp/vi.0AYKz3Lps7 658 vi 4 v r rw------- 1 0 - /var/tmp/vi.recover/vi.GaGYsz 658 vi 5 v r rw------- 1 0 - - PR: kern/173723 Suggested by: jhb

file and processes information retrieval from the running kernel via sysctl in the form of new library, libprocstat. The library also supports KVM backend for analyzing memory crash dumps. Both procstat(1) and fstat(1) utilities have been modified to take advantage of the library (as the bonus point the fstat(1) utility no longer need superuser privileges to operate), and the procstat(1) utility is now able to display information from memory dumps as well. The newly introduced fuser(1) utility also uses this library and able to operate via sysctl and kvm backends. The library is by no means complete (e.g. KVM backend is missing vnode name resolution routines, and there're no manpages for the library itself) so I plan to improve it further. I'm commiting it so it will get wider exposure and review. We won't be able to MFC this work as it relies on changes in HEAD, which was introduced some time ago, that break kernel ABI. OTOH we may be able to merge the library with KVM backend if we really need it there. Discussed with: rwatson

of the missing functionality from procfs(4) and new functionality for monitoring and debugging specific processes. procstat(1) operates in the following modes: -b Display binary information for the process. -c Display command line arguments for the process. -f Display file descriptor information for the process. -k Display the stacks of kernel threads in the process. -s Display security credential information for the process. -t Display thread information for the process. -v Display virtual memory mappings for the process. Further revision and modes are expected. Testing, ideas, etc: cognet, sam, Skip Ford Wesley Shields
